Step-by-step solution for: Phases of the Moon - Comprehension Worksheet | Teach Starter
You’ve uploaded three educational worksheets about the Phases of the Moon, designed for students to learn and test their understanding. Since you asked to “solve the problem and explain the solution,” I’ll treat this as a request to:
✔ Answer all questions on the third worksheet (the quiz)
✔ Explain each answer using information from the first two worksheets
✔ Clarify any misconceptions or tricky points

## 📝 Worksheet 3: Phases of the Moon — Quiz Answers & Explanations
---
Answer: a. Waning gibbous
> Explanation:
> The lunar cycle goes in this order:
> New Moon → Waxing Crescent → First Quarter → Waxing Gibbous → Full Moon → Waning Gibbous → Last Quarter → Waning Crescent → New Moon
> After Full Moon, the moon begins to shrink (wane), starting with the Waning Gibbous phase — where most of the moon is still lit, but a small sliver on the left side is darkening.
---
Answer: False
> Explanation:
> As stated in the first worksheet: *“Although sometimes the moon seems to be a light in the sky, it is not actually the moon that is giving off light. What you see is the sun’s light reflecting off the moon’s surface.”*
> The moon does NOT produce its own light — it reflects sunlight.
---
Answer: c. Waxing is when the moon appears to be getting bigger, while waning is when the moon appears to be getting smaller.
> Explanation:
> The second worksheet clearly defines:
> *“When the moon looks to be getting bigger, it is known as waxing. When the moon appears to be getting smaller, it is considered waning.”*
> So “waxing” = growing; “waning” = shrinking.
---
Answer: True
> Explanation:
> The first worksheet lists these 8 phases:
> 1. New Moon
> 2. Waxing Crescent
> 3. First Quarter
> 4. Waxing Gibbous
> 5. Full Moon
> 6. Waning Gibbous
> 7. Last Quarter
> 8. Waning Crescent
> So yes, there are 8 distinct phases in one complete lunar cycle.
---
*(This is an open-ended question — here’s the correct answer based on the text)*
> Answer:
> A lunar eclipse occurs when the Earth is directly between the moon and the sun, and none of the sun’s rays can hit the moon. This causes the Earth’s shadow to block sunlight from reaching the moon. A lunar eclipse can be seen from anywhere on the dark side of Earth.
> Note: The worksheet also mentions that a solar eclipse only happens when the moon blocks the sun’s rays — visible only from specific places on Earth.
---
Answer: b. Waning crescent
> Explanation:
> Looking at the chart in Worksheet 2:
> - Waning Crescent: *“A small crescent of the right side of the moon is lit while the rest is dark.”*
> So this matches perfectly.
> *(Note: “Right crescent being lit” means the lit part is on the right side — which is exactly how Waning Crescent is shown visually and described.)*
---
Answer: b. Old moon
> Explanation:
> The standard 8 phases are:
> New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent.
> “Old moon” is not a scientific term — it’s sometimes used informally to refer to the waning crescent, but it’s not an official phase.
---
*(Open-ended — here’s the correct answer based on the charts)*
> Answer:
> In the First Quarter, the right half of the moon is lit, and the left half is dark.
> In the Last Quarter, the left half of the moon is lit, and the right half is dark.
> Also, First Quarter occurs during the waxing phase (moon is growing), while Last Quarter occurs during the waning phase (moon is shrinking).
> *(Worksheet 1 and 2 both show this visually and describe it clearly.)*
---
Answer: False
> Explanation:
> As stated in Worksheet 1: *“A lunar eclipse can be seen anywhere on the dark side of Earth, but a solar eclipse can only be seen from specific places on Earth.”*
> That’s because during a solar eclipse, the moon’s shadow falls on only a small part of Earth — so you must be in that path to see it.
---
Answer: a. A lunar month has less days than a standard month.
> Explanation:
> Worksheet 1 says: *“In a lunar month, a day is slightly shorter than that of a standard month. A standard month is made up of 30.44 days, while a lunar month is only made up of 29.53 days.”*
> So a lunar month is shorter (~29.5 days vs ~30.4 days).
> Therefore, over 12 months, a lunar year is shorter than a solar (standard) year — which is why lunar calendars need adjustments (like adding leap months) to stay aligned with seasons.

## 💡 Teaching Tip:
These worksheets are excellent for visual learners — encourage students to draw or label the phases themselves, and use a flashlight + ball to simulate the Sun-Earth-Moon alignment!

1. Which phase should you expect to come after a full moon?
Answer: a. Waning gibbous
> Explanation:
> The lunar cycle goes in this order:
> New Moon → Waxing Crescent → First Quarter → Waxing Gibbous → Full Moon → Waning Gibbous → Last Quarter → Waning Crescent → New Moon
> After Full Moon, the moon begins to shrink (wane), starting with the Waning Gibbous phase — where most of the moon is still lit, but a small sliver on the left side is darkening.

2. The moon creates its own light.

Answer: c. Waxing is when the moon appears to be getting bigger, while waning is when the moon appears to be getting smaller.

6. Which phase of the moon is completely dark with the right crescent being lit?
Answer: b. Waning crescent
> Explanation:
> Looking at the chart in Worksheet 2:
> - Waning Crescent: *“A small crescent of the right side of the moon is lit while the rest is dark.”*
> So this matches perfectly.
> *(Note: “Right crescent being lit” means the lit part is on the right side — which is exactly how Waning Crescent is shown visually and described.)*
---
7. Which of the following is not a phase of the moon?
Answer: b. Old moon
> Explanation:
> The standard 8 phases are:
> New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter, Waning Crescent.
> “Old moon” is not a scientific term — it’s sometimes used informally to refer to the waning crescent, but it’s not an official phase.
---
8. How is a first quarter moon different from a last quarter moon?
*(Open-ended — here’s the correct answer based on the charts)*
> Answer:
> In the First Quarter, the right half of the moon is lit, and the left half is dark.
> In the Last Quarter, the left half of the moon is lit, and the right half is dark.
> Also, First Quarter occurs during the waxing phase (moon is growing), while Last Quarter occurs during the waning phase (moon is shrinking).
> *(Worksheet 1 and 2 both show this visually and describe it clearly.)*
---
9. A solar eclipse can be seen from anywhere on Earth.
Answer: False
> Explanation:
> As stated in Worksheet 1: *“A lunar eclipse can be seen anywhere on the dark side of Earth, but a solar eclipse can only be seen from specific places on Earth.”*
> That’s because during a solar eclipse, the moon’s shadow falls on only a small part of Earth — so you must be in that path to see it.
